COIN-OPERATED VENDING DEVICE.

SPECIFICATION forming part of Letters Patent No. 435,901, dated September 2, 1890.

Application filed October 24, 1889.

To all whom it may concern:

Be it known that I, DAVID OLMSTED, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Coin-Operated'Vending Devices, of which the followingis a specification.

My invention relates to certain new and useful improvements in coin-operated vending devices and particularly to amachine for vending postage-stamps. Machines of this general character are shown in Patent No. 414,950, granted November 12, 1889, and in :5 my application, Serial No. 307,229, filed April In my present improvement I provide for doubling the capacity of the devices shown in my former applications without materially 2o increasing the size, and I have also simplified the operation.

In the accompanying drawings,Figure 1 is a plan view of the device with a hinged lid thrown back. Fig. 2 is a plan view of the same with the cover closed, a portion of the casing being broken away. Fig. 3 is a side elevation of the device with a portion of the casing broken away. Fig. 4 is a broken perspective showing the coin-operated unlocking 0 devices.

In the drawings, A represents the lower portion of the case, at the upper rear edge of which is hinged the cover B. Within the case A is journaled the cylindrical receptacle 3 5 C, the periphery of which is divided into two circumferential compartments, each having slots b for the reception of the stamps. In the top of the cover is a delivery-opening D, and a hinged flap E is journaled transversely of said opening and midway of its length, so that the flap is adapted to close either half of the opening according as it is folded the one way or the other. The fiap E has on its lower side toward its upper end a locking-catch e,

5 which is adapted to be engaged by a springcatch member F, secured to the inside of the cover B.

G is a tripping projection, which is secured on the side of the stamp-receptacle C in such Serial No. 328,079- (No model.)

position as to engage the spring-catch F at one point of its revolution, whereby to release the hinged flap. \Vhen the stamp-receptacle is filled with stamps, the hinged flap or cover will be locked, so as to permit access to only one of the compartments of the receptacle C, 5 5 and by the rotation of said receptacle the slots containing the stamps will be brought successively beneath the uncovered portion of the opening in the cover to permit the removal of the stamps. The parts will be so set that when one compartment has been exhausted the tripping projection Gwill release the hinged fiap and permit access to the other compartment.

By the arrangement above described the 6 5 capacity of the device is twice that of the capacity described in my said former applications.

The operating mechanism is similar to that described in my said previous application and will now be described. Said operating mechanism includes a pin-wheel H, secured on the side of cylinder C, and having pins h projecting from the face thereof. I is a bar having a slot 1, through which the jour nal of the stamp-receptacle C is passed. This bar has a right-angled bend inside the casing, as shown in Fig. 2, and one of its ends is projected through the casing, where it is provided with a knob I. J is a retracting-spring having one of its ends secured to the casing and the other to the bar I.

Referring particularly to Fig. 4., K is a pivoted gravitydatch, one end of which has a right-angled bend provided with a slot k, and L is a slotted slide movably mounted on the slotted end of the latch and held in its normal position by the spring Z, secured with the latch.

In the normal position of the slide the two slots do not coincide throughout their length, a part of the slide being over the body of the bent end of the latch K. The slide is provided with a stud Z, and the bar I with a project ing arm I adapted to engage with the stud and actuate the slide in the forward movement of the bar I. M, Fig. 3, is a coin conduit or chute, which is so located as to direct the coin to the slot in the slide L. N is a fixed cam, and N a pivoted cam on the face of the bar I in position to engage with the pins 71. O is a retracting-spring secured at one end to the bar I and at the other to the pivoted cam, and which holds the same in its normal position in contact with the fixed cam. The outer endof the fixed cam has two angular converging surfaces, and the outer end of the pivoted cam is pawl-shaped. In the normal position of the bar I the fixed cam lies between two of the adjacent pins h, and the receptacle cannot be moved in either direction. On dropping the coin in the conduit it is passed into the slide L, and is there held until the bar I is moved forward. The weight of the coin depresses the end of the latch, and thereby frees it from engagement with the bar I, which is normally made by a lockingnotch i on the under side thereof. The bar, being thus freed, may be pushed inward until the pivoted cam is thrown into contact with one of the pins h, thus moving the stampreceptacle a half-step and bringing the next adjacent pin between the inner end of the pivoted cam and the adjacent inclined surface of the fixed cam. On releasing the knob the retracting-spring J returns the bar I to its normal position and the fixed cam comes in contact with the pin, which passes the point of the cam, and by this action forces the wheel around another half-step, the pin passing between the two cams and the fixed cam entering between two of the pins, thus locking the stamp-receptacle against further movement, except by a second operation of the bar.

It is obvious that the construction and arrangement of the parts may be changedas, for example, the flap may be made to slide in the delivery-opening, the receptacle may have more than two compartments, and the slots may be enlarged to contain other articles than stamps.

I claim- 1. In' a. coin-operated vending device, the combination, with an inclosing-casing having a delivery-opening in its wall, of a cylindrical receptacle rotatably mounted within said casin g and suitable mechanism for intermittingly rotatingthe same, saidreceptaclehaving itsperiphery divided into a plurality of circumferential compartments, each having slots to contain the articles to be vended, and a movable cover adapted to be locked in said opening over one of said compartments while the other is being emptied, substantially as described.

2. In a coin-operated vending device, the combination, with an inclosing-casing having a delivery-opening in its wall, of a cylindrical receptacle rotatably mounted within said casin g and suitable mechanism for intermittingly rotating the same, said receptacle having its periphery divided into a plurality of circumferential compartments, a flap hinged at one of its ends transversely of the delivery-openin g and having at its free end a locking-catch, whereby it is adapted to be secured in the opening over one of said compartments to prevent access thereto while the other is be ing emptied, substantially as described.

3. In a coin-operated vending device, the combination, with an inclosing-casing having a delivery-opening in its wall, of a cylindrical receptacle rotatably mounted within said casing and suitable mechanism for intermittingly rotating the same, said receptacle having its periphery divided into a plurality of circum ferentia'l compartments, each having slots to contain the articles to be vended, a flap hinged transversely of the delivery-opening and having a locking-catch projected from its free end, a spring-catch member secured with the casing, and a tripping projection secured with the rotatable receptacle, whereby the flap is released automatically at one point of the revolution of said receptacle, substantially as described.
